The EcoJohn Sr. is a waterless, incinerating toilet certified for safety by Underwriters Laboratories, which, for classification purposes, called it a barbecue.

"Toilets haven't really changed for the past 100 years," Stefan Johansson said. "People are always looking for better products, better solutions. The EcoJohns are better, cleaner and good for the environment."

The unit can be installed at a site as a primary toilet or carted via trailers and used as portable toilets.

The toilets, one of several waste disposal products offered by the company, operate pretty much like the units found in homes across America today. But while those toilets use water to carry waste away, the EcoJohn Sr. is equipped with a propane-fueled burner.

After a user does his business, he closes the lid and a large, screw-like auger turns and carries the waste to the burn chamber where the propane burner then bakes urine, feces and paper into ashes.

The EcoJohn is useful for places where it is impractical to install a sewage system, such as vacation cabins, rooftop parties, and construction sites. But the question in everyone's mind is: why does it have to be classified as a barbecue?! Link-Thanks, Julie Anne!
